The Chambers family has a net monthly income of $6,500. Chambers Family Budget:

Savings 7%

Clothing 18%

Medical 10%

Emergency Fund 8%

Transportation 12%

Food 20%

Housing 25%

If the family decides to reduce its clothing budget by $200 a month, how much would the new clothing budget be? Round to the nearest dollar.

$161

$853

$970

$1,170

### Answers

Answer:

Option C $970 is the new clothing budget.

Step-by-step explanation:

The Chambers family has a net monthly income = $6,500

Chambers family budget for Clothing = 18% of net income

= (18/100) × 6500

= 0.18 × 6500 = $1,170.00

The budget of Chambers family is $1,170.00 per month, Now the family decides to reduce its clothing budget by $200 a month.

Therefore, we subtract $200 from his old budget to get new clothing budget.

1,170 - 200 = $970.00

Now the new clothing budget of the family is $970.

.18 x 6500 = 1170

1170 - 200 = 970

Answer = $970

Dima called her friend to tell her that she saved 30% on her new skirt at a discount store. Her friend told her that she could have gotten a better deal at a different store that was advertising a sale of 1/3 off all clothing. If the original price of Dima’s skirt was $54, how much more could she have saved at the store her friend suggested? A) $1.11

B) $1.80

C) $36.00

D) $37.80

### Answers

Tbh i Would prolly go B,

54*0.3 (30%) is 16.2

54*(1/3) is 18

18-16.2 is 1.8 or $1.80

The equation of a circle is(x-3)^2+(y+8)^2=36. Relative to the standard equation of a circle (x^2+y^2=r^2), how has this circle been shifted? What is the radius of the circle?

### Answers

The circle shifts to the right 3 units and down 8 units. It's radius is 6

The circle has been shifted 3 units to the right and 8 units down.

The radius of the circle would be square root of 36, which is 6

Radius= 6 units

Translation= 3 units horizontally right , 8 units vertically down

Hiram raises earthworms. In a square of compost 4 ft by 4 ft, he can have 1000 earthworms. How many earthworms can he have if his square of compost has a side length that is 8 times longer?

### Answers

Answer:

The answer is 64000.

Step-by-step explanation:

Given is -

Hiram raises 1000 earthworms in a square of compost 4 ft by 4 ft.

When the square of compost has a side length that is 8 times longer, means the area will increase by a factor of times.

So, total earthworms will be =

64,000 I believe. What I did was find the area so 4*4 =16. 1000/16 = 62.5 earthworms per square foot. So if the side is 8 times longer then 8*4= 32 feet per side and to find the area of that it's 32*32 = 1024 feet squared. So 62.5 * 1024 =64,000

### Answers

The fraction of the bag left is 5/12

Fraction

From the question, we are to calculate the fraction of the bag left

From the given information,

There is 2/3 of a bag of jelly beans

Then,

Danny ate 1/4 of this

The fraction of the bag that would be left would be

Solving

This is the fraction of the bag left

Hence, the fraction of the bag left is 5/12

In a high school of 1250 students, 250 are freshmen and 150 students take Spanish. If being a freshman and taking Spanish are independent, what is the probability that a randomly selected Spanish student is a freshman? A)0.024

B)0.120

C)0.150

D)0.200

### Answers

D. Because one fifth of students from the school are freshmen since 250/1250 = 1/5. Since taking Spanish doesn't depend on your grade level we can assume that one fifth of the students taking Spanish will be freshmen as well

George invested $2000 at two different rates, 5% and 6%. If his total interest income was $106 how much did he invest at each rate?

### Answers

Given:

Total investment = $2000

rate 1 = 5%

rate 2 = 6%

Total interest income = $106

let x = investment at 5%

2000 - x = investment at 6%

$106 = A1 + A2

A = P(i(1+i)^n/ (1+i)^n -1)

Assume n = 1
